Understand the Problem
The question is asking about the defining characteristics shared by all organisms belonging to the phylum Ctenophora. This requires identifying the key features that distinguish this group of animals.

Key characteristics of Ctenophora: free-living marine organisms, diploblastic, and colloblasts for prey capture.
Key characteristics of Ctenophora include: being free-living marine organisms, having two embryonic layers (diploblastic), and possessing colloblasts (sticky cells for prey capture). They exhibit biradial symmetry and move using comb-like ciliary plates.

More Information
Ctenophores, commonly known as comb jellies, are a phylum of marine invertebrates. They are more primitive than jellyfish.
Tips
A common mistake is to confuse Ctenophora with Cnidaria (jellyfish, corals, and sea anemones). Ctenophora have colloblasts instead of cnidocytes (stinging cells) which cnidaria use.
